rThis invention relates to protecting devices tor pneumatic tires; andit has vloi' its object to so construct a contrivanee of this characterthat it shall comprise on its. edges, provided for that purpose with hatflanges, hooliing devices of peculiar shape designed to setire, whileavoiding the wear and tear to which the protecting devices now' in useare subjected on account olt tl'ie continuons strain to which the usualhooking and fixing devices give rise.

ln the accompanying drawings, which show, hy wav of example, twoembodiments of this invention, Figure 1 is t cross-sectional view o'l apneumatic tire provided with a protecting il ivice having flanges orheels and hooks. Fig-s. 2 and 3 are respectively an Figs. -l and 5 are asectional and plan view ol' a poi'- tion of a protecting device providedwith hooks of another shape.

As shown in Fin. the protectinp` device 1 is of suilicient width toallow of its edges lieing engaged between the flanges 2 of the rini andthe flanges niatic tire. 'llhe said edges are pii'ividcd with. llatthing-es e, extending; along the whole of the circumference andoutwardl)Y at right anglee, or nearly so, with respect to the lateralportions of the protecting device, Fig'. l Shows how the said flanges itare nipped hetween the flanges 2 ol the rim andthe llanges or heels ofthe cover o'l" the pneuniati tire.

ln each of the edges are secured at intervals i y metal hooks o,designed to he applied against the langes -2 of the rim in ori'ler tohold or maintain the prete'ctingr device in place. Each hook 5 ee Figs.2 and 3) consists ot a plate, preferablyv ol' sheet-steel, #so lient asto beoi 5? or 2 shape in crosssection. One of the edges of the saidplate is provided with teeth 5, designed to penetrate into the materialof the 'irotectin device in order to se-' cure the hook in the saine.For that purpose of the cover ol the pneu-- 'ing device and -reicrenceto i" of the protecting device is engaged in the lng` il 7 ol" thehoch', and then the eight is closed down, shown in llir. l. The otherhight fil lies :it the ontsidcot tne protectniust 'he engaged en theflange 2 of the rim. The lower portion 7 is, moreover, prolongedlaterally bevond the teeth 6 to provide room 'for two rivets whichcoinplcte the devices lorsecuring,l tl hook onto the protecting device.

"afl/inni the pneumatic tire is mounted, the portion T of .the hook issecurelyv clamped lietween tie llange 2 oill the iiin and the flange orheel il olt l cover ci the pneumatic tire,

and it l 'from swingin y the h ahn'ls eriac'i'h: on the the portion oikthe hoolis are rent e, inodilfd torni shown in 5 the hook is t; shaped.its single oi 4 is designed to ahnt on the flange ol' the rini inexactly the saine manner as in the previous ase lhe said hoolt issecured liv .its il l' portion on edge. of the protecting d vice hvmeans or rivets (l. l'llhen the protecting device z engaged between theVini and the flanges or lniels v" t or' the pneumatic Y1 i i the covetire, the nonies thus arranged playY absolutely the saline part es thehooks 5, described .in

Il ilhher pi'otcctn j devices the are prel'crfihly olilaiiied iiitegral:retellingdevice when molded.; but they may also he attached lo theedges ol the protecting deaf'ice. Finally, the invention isai'ii'ilica'nie also to those protectinc,v devices iii parts calledsleeves or gaiter-sleevcs and which are used lo cover a danniged partci" the pneumatic tire,

, iroin which they are made, the naturev claim Ll.. A protecting devicefor pneumatic tires, formed by c strip of suitable materiel which is ofsu'icient width to wrap the cover of the pneumatic tire and to hesecured 1between the fia-nge of the rim and the flange ofthe seid cover,end which is provided. with Het heels recticnlly at right angles withrespect to the ihterel portions; end hooking devices each compdsed ,ofs., metal plete having an outwardly-opening hight abutting on the ilcngeof the rim ol" the wheel end provided with ineens by which it is securedto the Flange oi" the protecting device. i

2. A protecting device ot c. width enabling` it to Wrap the cover of thepiieuma-tic tire, Hanges formed at right angles on its edges to henipped between the litnge ot the rim and the flange of the cover, andhooking devices each `formed of e motel plete provided with e bight tovabut on the flange of the rim and with a second bight to chut on theflange or heel of the protecting device, with means for Securing thesecond Sloi'ght on the protecting device. l i

3. In vehicle-wheels'provided with neumetic tires, e protecting deviceof sui icient width to be enabled to wrap the pneumatic tire, flangesformed etv right :ingles on its edges, and hooking devices each Vformedoi e metal plete provided with two hights opening in oppositedirections, the one to chut on' the flange of the protecting device, andthe other and wider .bight to clout on the flange of' the rim of thewheel.

' 4. in e. vehicle-wheel havingn e, pneumatic tire, c. hook to sec-nreon the rime protecting device provided with flanges, which hool; isformed of a metal plete provided with c big-llt to abut on the rim oithe wheel end with a second bight to :ibut on the finnge o'l theprotecting device, with rivet-holes and u teeth to secure the seme onthe protecting device.

5. The combination With the rim et' e vehicle-wheelhaving;inwardly-extending enges at its side edgee, e pneumatic tireendcover ineens for etteci'iing the plete to the protectingl device Whereseid device is located `oetween the yrim end 'the cover ienges.

6. A vehicle-Wheel having forwerdiyeextending flanges at `its outer sideedge; e. pneumatic tire having outwardly-extending side ienges locatedbeneeth the iienges of the rini, e protective covering 'for the tire,having its longitudinal edges cerri'ed outward end nipped between theflan es of the. rim endthe flanges of the tire, en locing devices forthe protective coverinc, consisting of metal plates `p'rovided withLtights which receive the flanges of the rim and highte whic receive thelongitudinal edges or the protective covering, and means for securingthe second hights to lthe seid protective covering.

in tjestlniony that l claim the foregoing es my invention I have signedmy naine in presence oi. two subscribing witnesses.
